Okay, the chef at my work thought sharks were a type of dinosaur and me and another guy just spent several hours trying to make him understand that while physically things are generally finite the concept of infinity is in fact real. He explained the science, I went more philosophical and explained the concept is real because we're discussing it. You know in Sci fi when they use a machine to go into someone's brain and it's conceptualized as a weird hallway or whatever? This is one I'm super intrigued to do that if possible and also deeply terrified.
